Discussion | Ceanothus lemmonii occurs in the inner North Coast Ranges, Klamath Mountains, and the western slope of the Cascade Range and northern Sierra Nevada. H. McMinn (1944) reported putative hybrids with C. foliosus, C. integerrimus, and C. oliganthus var. sorediatus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ceanothus herbaceus is an older name than C. ovatus, which has been used widely in botanical and horticultural literature (G. K. Brizicky 1964c). Plants with persistently puberulent leaves occur principally east of the Mississippi River Valley and have been called var. pubescens, but the extent of intergradation occurs over a broad geographic area and deserves further study (N. C. Coile 1988). Putative hybrids between C. herbaceus and C. fendleri in the eastern foothills of the Rocky Mountains were named C. ×subsericeus Rydberg.
